YASNAC PLC Edit

Hello together,
did anybody know if it is generally possible to simple edit the PLC ( Hitachi VM40II '85 Yasnak control propably LX3 )
I have to move a logical output to another Output pin because one bank is shot, but there are spare outputs
Repair of the I/O Board is about $1000

e.g. #11050 to #11070
With simple edit I mean not to burn a EPROM
Any suggestion would be welcome

Re: YASNAC PLC Edit

Not sure if this ladder is part of the Hitachi side of things or is it really part of the Yasnac control side. Hitachi made alot of design changes seems like based on what control boards were available when they built the machines.
